Business transactions as well as government treasury operations were also impacted.
The United Forum of Bank Unions (UFBU), consisting of nine bank unions -- AIBEA, AIBOC, NCBE, AIBOA, BEFI, INBEF, INBOC, NOBW and NOBO -- had given the strike call to protest against the government's decision to privatise two more public sector lenders.
"Strike was a full success, employees and officers stood with us. The way they participated and raised slogans, it shows their disapproval of the government decision very clearly.
"We got support from all trade unions, some farmer organisations, lot of political parties have supported us," AIBEA General Secretary C H Venkatachalam told PTI.
